This file is to help you use this routine.
|
||
Since our ink screens are getting more and more, it is not convenient for our maintenance, so all the ink screen programs are made into one project.
|
||
A brief description of the use of this project is here:
|
||
|
||
1. Basic information:
|
||
This routine was developed based on the jetson-nano-sd-r32.1-2019-03-18 system
|
||
image. Since the current system does not have a hardware SPI,Currently developed
|
||
with analog SPI, so the ink screen refresh rate is slower;
|
||
This routine was developed based on the Jetson Nano and the routines were
|
||
verified on the Jetson Nano;
|
||
This routine has been verified using the e-paper Driver HAT module.
|
||
You can view the corresponding test routines in the examples\
|
||
of the project.
|
||
|
||
2. Pin connection:
|
||
Pin connections can be viewed in \lib\epdconfig.py and will be repeated here:
|
||
EPD => Jetson Nano/RPI(BCM)
|
||
VCC -> 3.3
|
||
GND -> GND
|
||
DIN -> 10(SPI0_MOSI)
|
||
CLK -> 11(SPI0_SCK)
|
||
CS -> 8(SPI0_CS0)
|
||
DC -> 25
|
||
RST -> 17
|
||
BUSY -> 24
|
||
|
||
3.Installation library
|
||
sudo apt-get update
|
||
sudo apt-get install python-pip
|
||
sudo apt-get install python-pil
|
||
sudo pip install Jetson.GPIO
|
||
|
||
or
|
||
|
||
sudo apt-get update
|
||
sudo apt-get install python3-pip
|
||
sudo apt-get install python3-pil
|
||
sudo pip3 install Jetson.GPIO
|
||
|
||
4. Basic use:
|
||
Since this project is a comprehensive project, you may need to read the following for use:
|
||
You can view the test program in the examples\ directory.
|
||
Please note which ink screen you purchased.
|
||
Chestnut 1:
|
||
If you purchased 5.83inch e-paper, then you should execute the command:
|
||
Sudo python epd_5in83_test.py
|
||
Chestnut 2:
|
||
If you buy a 2.9inch e-paper (B), since the 2.9-inch Type B and Type C are common driver codes,
|
||
Then you should execute the command:
|
||
Sudo python epd_2in9bc_test.py
|
||
|
||
Note: For epd_1in54_V2_test.py and epd_2in13_V2_test.py, please note that the V2 logo is attached to the back of your screen.
